Summary: The Palmaz Biliary Stent is a device used primarily for biliary duct obstructions. Key evidence highlights its use in managing acute recoil and AV fistula repair.
The Palmaz Biliary Stent was cleared by the FDA via the 510(k) pathway on February 5, 1991. It is manufactured by Johnson & Johnson Interventional Systems and classified as a Class 2 device.
What It Is
The Palmaz Biliary Stent is a metallic stent designed to maintain patency in biliary ducts. It is used in interventional procedures to prevent or treat obstructions.
Clinical Applications
Commonly used in the management of biliary obstructions, the Palmaz Biliary Stent is also applied in vascular interventions, such as addressing acute recoil and repairing arteriovenous fistulas.
Evidence Summary
The literature includes three studies from 1996 to 1998, focusing on various applications of the stent. These studies explore its use in coronary, vascular, and neurovascular interventions.
Reported Outcomes
Published studies report that the Palmaz Biliary Stent effectively manages acute recoil in coronary stenting and repairs popliteal arteriovenous fistulas. It also supports carotid angioplasty, potentially preventing strokes.
Safety Profile
Reported complications include acute elastic recoil in coronary applications, which can be managed with additional stenting. No other specific adverse events are detailed in the provided studies.
Evidence Limitations
The evidence is limited to a small number of studies with specific clinical scenarios. Further research is needed to generalize findings across broader patient populations and clinical settings.
